How to configure "mention" with Microsoft Team Graph spoke when Post Message?

[oster]

Hello,

Has anyone been able to post a message to teams with a mention? I cannot get this to work, the part of my post which is suppose to be the "mention" is just free text. Im not sure exactly what needs to be populated in the mention parts, as its just data-pills allowed.

The pre-processing part looks OK for mention but then in the Post body it seem that the mention is not formatted correct. 

Thankful for any assistance in this matter.

Post-body after test:

I have now solved this. I had the "title" field populated in my Post Message. When the title is populated, mentions is not supported as the title will create a Thumbnail Card in Teams. Leaving the title field empty mention works fine.

Are you able to share a screen shot of the full action and XML(?) to see the whole context of a working action withe mention.
